The objectives of this study were to determine the morphological varieties of Amorphophallus and to classify them into the clusters according to their similarities in phenotypic or morphological characters. The phenotypic characters that had been observed consist of total plant height, the canopy or lamina width, upper and lower petiole circumference, pattern of the petiole (shape of the spots, color and number), tuber weight, diameter of the tuber (transverse and longitude), color of the tuber, the presence of bulbils, leaflet form, leaf color, leaflet venation and the ratio of the length and width of leaflets. There were 12 variants found in the research location; four were classified into A. campanulatus, six variants were classified into A. variabilis and two variants were classified into A. muelleri. The data showed the varieties of morphology in Amorphophallus were not quite large based on several morphological characters values. Based on the cluster analysis, there were three major clusters formed due to the similarities and dissimilarities of their morphology. The first cluster contained A. campanulatus 1, 2 and 3, the second cluster contained A. variabilis 1, 2, 3, 4, 5, 6 and A. campanulatus 4, meanwhile, the third cluster contained A. muelleri 1 and 2.
